Description:

Breed pea plants to observe flower color.

Transcript:

HI!
You are using pea flower color as an eighth trait to do plant breeding experiments like Mendel. You have a pure-bred colored flower plant and a pure-bred white flower plant.
What will the F1 progeny be like if you cross-fertilize the colored flower plant with pollen from the white flower plant?
The plants in the F1 generation will have either colored or white flowers if one trait is dominant. That is correct.
All the plants in the F1 generation will have pale colored flowers. No, all the plants in the F1 will be pale-colored if neither trait is dominant.
There will be plants that have all three flower colors: white, pale colored and colored flowers. No, all the flowers of one plant will have the same color.
If the colored flower plant is cross-fertilized with pollen from the white flower plant, in the F1 generation, plants will either have colored or white flowers, if one of the traits is dominant.
Let's try another cross. This time let's cross-fertilize the white flower plant with pollen from the colored flower plant. What will the F1 progeny be like?
All the plants in the F1 generation will have pale colored flowers. No, all the F1 flowers will be pale colored if neither trait is dominant.
The plants in the F1 generation will have either colored or white flowers if one trait is dominant. No, all the F1 flowers will be pale colored if neither trait is dominant. That is correct.
There will be plants that have all three flower colors: white, pale colored and colored flowers. No, all the flowers of one plant will have the same color.
In the F1 generation, plants will either have colored or white flowers, if one of the traits is dominant. In a cross between two pure-bred plants with different alleles for the same trait, it doesn't matter which plant contributed the pollen or the egg, the results are the same.
